I can't say enough to recommend this company! Thank you!

Marcus came out same day, within a few hours literally 30 mins outside Yreka to fix our heat pump…read morefurnace. Another gentleman was with him, his name started with an R, like Raymond or Ramon. I am really bad with names but the reason I can actually remember any of the names is because of how positive of an experience this was. They basically came out, diagnosed it within an hour and had the part replaced because they had it on hand in their truck. It was some kind of electrical switch. They tested the system and it's been working ever since! The price was very affordable and service was A+. I'll recommend this crew to everyone interested. They shook my hand and were very respectful gentlemen. Not to mention, if anyone goes on the Next door app, our neighbors in Lake Shastina neighborhood suggested Marcus and a "Raymac." Not just once, like a half dozen people and more than 80% of the comments were all about mountain Air and Marcus. Credit is earned where it is due. Thank you gents! ​​

Awesome service!

Charlie, who delivers from Blue Star Gas is very rude and impatient. I have a locked gate to…read moreprevent my dogs from escaping. When Charlie arrives, I unlock the gate. This time, I was in the restroom when he arrived. He stated he arrived at 9:25am, as you can see in the attached photos. I made the attempt to call him immediately after hearing him ring the doorbell, so he would be aware of me being in the restroom. I even got notified on my ring camera if him leaving a minute later at 9:26am, as shown in the picture. I tried flagging him down, yelling his name, and calling him as he started his truck and took off. Very frustrating and unprofessional. I never had issues with the last representative that delivered, but with Charlie, it has been miserable. Because of this, I have canceled services and went with another gas company that is going to service for 2.47 per gallon. So in a way, this is also saving me more. Win win. Bye-bye blue star.

One year they put a meter on my tank that reports levels back to the office, how convienent is that. Adam calls me when I get down to 20%, how thoughtful. You could say they do these things just to sell more fuel, until you run out and you have to take a cold shower. Over the years I've seen Blue Star Gas get better and better and I'm a fan. In life or business, you're either getting better or getting worse. Over 3 decades Blue Star Gas has done just that. I bake them cookies because I admire how they service the Mount Shasta residents.

Even though he was very busy, he came out as soon as he could. He showed up on time for our appointment in a clean organized truck,. (I always check for this because an organized truck is an organized mind. It tells me something about the contractor.). He ran tests and checked out all of the equipment. He was very thorough and persistent in locating the problem. Turned out we needed a part, which he ordered and installed the day after it came in. In addition to being knowledgeable and professional, Ernie is a very likable person. We're very grateful to him for getting to us as soon as he could because we do not have a fireplace or wood stove. I have recommended him to all of my neighbors and friends. I know who we will be calling for all of our HVAC issues from now on. Thanks, Ernie!
